NUMERICAL APPROACH TO TWO-LOOP THREE POINT FUNCTIONS WITH MASSES

High Energy Physics - Phenomenology 2011-03-02 v2

Abstract

Extending the method successful for one-loop integrals, the computation of two-loop diagrams with general internal masses is discussed. For the two-loop vertex of non-planar type, as an example, we show a calculation related to Z0ttˉZ^0\rightarrow t \bar t vertex.
